Stress has long been suspected as a possible cause of early miscarriage, but there's little evidence to support the theory.
Up to 20 percent of known pregnancies end in miscarriage. Typically, early miscarriage is caused by a fetal chromosomal abnormality or another problem in the development of the embryo.
Possible causes of repeated early miscarriage might include:
- Abnormalities of the uterus
- Immune responses that disrupt implantation
- Hormone imbalances
- Blood-clotting problems
If you're concerned about early miscarriage, concentrate on taking good care of yourself and your baby. Seek regular prenatal care, manage any chronic conditions and avoid known risk factors for miscarriage — such as smoking and drinking alcohol.
